Imagine that you have a client that works as a professional clown. In this imaginary scenario, your client would want to know that his clown uniform, from the oversized shoes to the red nose, is deductible from his tax return. It turns out that these items are not usable anywhere else and, therefore, are officially labeled tax deductible.

(In case you’re wondering if that law also applies to horrible bridesmaid dresses: No, dear bridesmaid, you may not be able to wear that green satin nightmare anywhere else, but you won’t receive a tax perk for your sacrifice.)

We combed the Internet to find the weirdest tax laws out there, from odd deductions to strangely specific taxations. Here are some of the findings.

In the United States:

1. The professional bodybuilder tax deduction

According to Investopedia, the Internal Revenue Service (IRS) will allow taxpayers in certain professions to deduct expenses related to their physical appearance. The article, which you can read here, says that the tax courts have ruled that bodybuilders can deduct the cost of body oils and other products that they use to enhance the appearance of their skin.

They can’t deduct every work-related expense, however. Another article in The Fiscal Times says that a professional bodybuilder can’t deduct the “wheatgrass shots and buffalo meat he eats to tone his form.”

2. The starving artist tax deduction

LearnVe$t, a financial planning company that sells software, notes that performing artists can get a deduction for expenses incurred under certain circumstances. These circumstances include: “… [having] at least two employers, and receiving at least $200 in income from each; [incurring] job-related expenses that are more than 10 percent of income from performing artist jobs; and [having] an adjusted gross income that does not exceed $16,000. If they meet those requirements, they can deduct art-related expenses.”

3. The “hosting an exchange student” tax credit

Investopedia says that if you are hosting a student from a foreign country, then you may be eligible for a monthly tax credit of up to $50. Several conditions must be met in order to qualify for this credit. First, the taxpayer must have an official agreement with the organization that is sponsoring the exchange program, and that organization’s reason for existence must be either solely or primarily to provide educational opportunities and experiences for its students, the article says. The exchange student must also be a full-time high school or secondary school student and cannot be a relative or family member of the host.

4. The “jock tax”

TurboTax, the tax preparation software company, recounts that back in 1991, the state of California imposed a new tax after the Chicago Bulls beat the L.A. Lakers in the championship finals. The tax consists of taxing sports celebrities, performers and other entertainers who generate money, and was subjected as California State Income Tax.

Since it was originally enacted in California, additional states have adopted the “jock tax.”

5. A tax on litigation

According to efile.com, a tax filing software company, in Tennessee, there is a tax on all litigation. The amount varies case-by-case but it can be as low as $1 for a parking violation case. The tax is designed to discourage frivolous lawsuits.

6. People over 100 years old are tax-exempt in this state

Are you or your loved one over 100 years old? Then New Mexico might be looking really good right about now: Centenarians are exempt from New Mexico state income tax, according to efile.com, a tax filing software company. The one caveat is that the person can’t be classified as a dependent.

Around the world:

7. The window tax

Taxing architecture has been a common practice throughout human history. One of the many examples includes the seventeenth-century United Kingdom, where it was common practice to impose a “window tax.” The idea behind this was to tax the wealthy, who generally lived in nicer houses with more windows.

To a certain extent, this plan backfired. An article on efile.com points out that the tax led to many houses having very few windows in order to avoid paying the tax, which eventually aroused health concerns and led to the tax’s repeal in 1851.

8. A tax on political opponents, aka the “decimation tax”

Can you imagine if President Barack Obama suddenly decided to impose a tax on everyone and anyone who isn’t part of the Democratic Party? I think the whole country would be up in arms, but that’s exactly what Oliver Cromwell — an English military and political leader who later became Lord Protector of England, Scotland and Ireland in the 1600s — did to his political opponents, the Royalists.

The tax took one-tenth of the Royalists’ property, and the money was used to fund Cromwell’s activities against the Royalists, according to a paper on the University of Wisconsin website.

9. Baby names have to approved by a tax agency

You read that right! In Sweden, all baby names need to be submitted and approved by the Swedish tax agency, before the child turns five years old. This, according to an article on CNBC, which also explains that the law was put in place to prevent people from using royal names or selecting an offensive or confusing name.

Some names like “Ikea” and “Allah” have been rejected. One set of parents tried to protest the law by submitting the following name: “Brfxxccxxmnpcccclllmmnprxvclmnckssqlbb11116.” The Swedish tax agency shut that one down, too.

However, CNBC says that the Swedes overwhelmingly have a positive view of their tax agency, according to a 2013 survey that found that, among government agencies, the tax agency had the second-best reputation in the country, with an 83 percent approval rating.

10. The “how wide is your house” tax

In Amsterdam, there used to be a tax on the width of the canal-facing front of your house. Initially, the tax was imposed to raise money for the city’s expansion project. So, how did people get around it? They built the now-iconic narrow houses that line Amsterdam’s canals — which are also quite deep, allowing residents to lower their taxes without sacrificing space.

The narrowest house in all of Amsterdam is no longer than 5 feet wide on the front and almost the same width on the back, according to website Amsterdam.info. I’ve seen TVs wider than that!
